Since broadcast frequencies are very limited in number, these objectives are to some extent inconsistent in that not all of them can be fully realized, and to the extent that each is realized, there is a corresponding reduction of the possibilities for fullest achievement of the others.

Since then, there has been a notable increase in the number of stations and also the accumulation of additional data and the development of new techniques for using it, leading to a better understanding of propagation phenomena.

Since is the distance from a given number to the mean, one way to interpret this property is as saying that the numbers to the left of the mean are balanced by the numbers to the right of the mean.

The number of neutrons, N, is known as the neutron number of the atom ; thus, A = Z + N. Since protons and neutrons have approximately the same mass ( and the mass of the electrons is negligible for many purposes ), and the mass defect is usually very small compared to the mass, the atomic mass of an atom is roughly equal to A.

Since the number of possible sounds in all of the world's languages is much greater than the number of letters in any one alphabet, linguists have devised systems such as the International Phonetic Alphabet ( IPA ) to assign a unique and unambiguous symbol to each attested consonant.

Since the elements can be uniquely sequenced by atomic number, conventionally from lowest to highest ( as in a periodic table ), sets of elements are sometimes specified by such notation as " through ", " beyond ", or " from ... through ", as in " through iron ", " beyond uranium ", or " from lanthanum through lutetium ".

A set S is called countable if there exists an injective function f from S to the natural numbers Since there is an obvious bijection between and it makes no difference whether one considers 0 to be a natural number of not.

) Since Popes can dispense from church laws, they have sometimes brought the number of cardinals under the age of 80 to more than 120, perhaps calculating that the number would be sufficiently reduced by the time the need for a conclave would arise.

Since then, a number of Australian states have introduced or tightened importation regulations.

Since a medieval spear required only a small amount of steel along the sharpened edges ( most of the spear-tip was wrought iron ), it was an economical weapon.

Since beams typically do not have sharp edges, the diameter can be defined in many different ways.

Since the Great Salt Lake is a shallow lake with gently sloping shores around all edges except on the south side, small variations in the water level greatly affect the extent of the shoreline.

Since diamonds are very hard to cut, special diamond-bladed edges are used to cut them.

Since the edges of the Orbital are built as high walls, the rotation prevents the atmosphere from escaping, thus protecting the inhabitants from radiation.

Since TV screens hide the vertical blanking interval of a composite video signal and even crop the edges of the picture, extensions have been implemented by taking advantage of these unseen parts of the signal.

Since they each formerly had an odd number of edges, they must now have an even number of edges, fulfilling all conditions.

Since all the eigenvalues are non-negative, the problem is convex and the maximum occurs on the edges of the domain, namely when and ( when the eigenvalues are ordered in decreasing magnitude ).

Since each edge is defined by two endpoint vertices, and we only enumerated the interior vertices, group 2 edges are counted twice while group 3 edges are counted once only.

Since Max Payne, the polygon count ( the number of polygons rendered per frame ) has been increased, which smooths out the edges of character models.

Since the part is blanked in one operation, the finish edges of the part produces a uniform appearance as opposed to varying degrees of burnishing from multiple operations.

Since the laminar flow of a moving body of water carves the path of movement, it experiences friction caused by resistance along the shallows and outer or higher banks, and travels at a slower speed at the edges than the center.

Since our first appearance in San Francisco on Easter Sunday, 1979, the Sisters have devoted ourselves to community service, ministry and outreach to those on the edges, and to promoting human rights, respect for diversity and spiritual enlightenment.

Since barycentric coordinates are a linear transformation of Cartesian coordinates, it follows that they vary linearly along the edges and over the area of the triangle.

Since that time, the relentless force of running water has eroded the geologic layers, resulting in older rocks becoming exposed in the middle of the Swell, and younger rocks exposed around the edges.

Since the Ice Age, the mouth of Klarälven has moved from Forshaga to its current position at Karlstad, and is still moving, albeit for different reasons, as the river carries substantial quantities of sand, cut from the outer edges of its meandering curves, causing the shoreline of Vänern to constantly move southward.

Since this graph has Θ ( n < sup > 2 </ sup >) edges for n distinct points, constructing it already requires Ω ( n < sup > 2 </ sup >) time.

Since there are O ( n ) edges, this requires O ( n log n ) time using any of the standard minimum spanning tree algorithms such as Borůvka's algorithm, Prim's algorithm, or Kruskal's algorithm.

Since the plating is now done after the blanks are punched, the edges of the modern coins receive the plating.

Since each node has degree k, there are edges remaining for each Level 1 node to connect to nodes in Level 2.

Since 1-arcs are simply edges, every symmetric graph of degree 3 or more must be t-transitive for some t, and the value of t can be used to further classify symmetric graphs.

Since most arenas in the genre take up more than the width of one screen, and many are depicted as out in the open and away from confinements, especially on the edges, this may result in a character wall jumping off an invisible barrier rather than an actual in-game wall — and a temporary one at that, once action scrolls back past it.
